OBJECTIVE To explore the effects of Xingnaojing injection on cerebral edema and blood-brain barrier (BBB) in rats following traumatic brain injury (TBI). METHODS A total of 108 adult male Sprague-Dawley rats were used as subjects and randomly assigned to three groups: sham-operation, TBI and Xingnaojing injection groups (10 ml/kg/d, intraperitoneal injection). TBI in rats was set up by the improved device of Feeney's weight-dropping model with the impact of 600 g.cm. Brain water content and BBB permeability expressed as Evans blue content were measured at 1, 3, 5 and 7 days after surgery. RESULTS In sham-operation group, brain water content and Evans blue content in brain tissue were 78.97%+/-1.22% and 5.13 microgram+/-0.71 microgram. Following TBI, water content in brain tissue was increased significantly at 1, 3, 5 and 7 days (83.49%+/-0.54%, 82.74%+/-0.72%, 80.22%+/-0.68%, 79.21%+/-0.60%), being significantly higher than that in sham operation group (P less than 0.05). Evans blue content was increased in TBI group (16.54 microgram+/-0.60 microgram, 14.92 microgram+/-0.71 microgram, 12.44 microgram+/-0.92 microgram, 10.14 microgram+/-0.52 microgram) as compared with sham-operation group(P less than 0.05). After treatment with Xingnaojing injection, brain water content decreased as compared with TBI group (81.91%+/-1.04%, 80.38%+/-0.72%, 79.54%+/-0.58%, 78.60%+/-0.77%, P less than 0.05). Xingnaojing injection also reduced the leakage of BBB as compared with TBI group (15.11 microgram+/-0.63 microgram, 13.62 microgram+/-0.85 microgram, 10.06microgram+/-0.67 microgram, 9.54 microgram+/-0.41 microgram, P less than 0.05). CONCLUSIONS Xingnaojing injection could alleviate cerebral edema following TBI via reducing permeability of BBB.

D001921 Brain The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon
D001929 Brain Edema Increased intracellular or extracellular fluid in brain tissue. Cytotoxic brain edema (swelling due to increased intracellular fluid) is indicative of a disturbance in cell metabolism, and is commonly associated with hypoxic or ischemic injuries (see HYPOXIA, BRAIN). An increase in extracellular fluid may be caused by increased brain capillary permeability (vasogenic edema), an osmotic gradient, local blockages in interstitial fluid pathways, or by obstruction of CSF flow (e.g., obstructive HYDROCEPHALUS).

D001930 Brain Injuries Acute and chronic (see also BRAIN INJURIES, CHRONIC) injuries to the brain, including the cerebral hemispheres, CEREBELLUM, and BRAIN STEM. Clinical manifestations depend on the nature of injury. Diffuse trauma to the brain is frequently associated with DIFFUSE AXONAL INJURY or COMA, POST-TRAUMATIC. Localized injuries may be associated with NEUROBEHAVIORAL MANIFESTATIONS; HEMIPARESIS, or other focal neurologic deficits.
